Abstract (en)
[origin: WO2006060831A1] A method for modifying the polarization state of light with a magnetically uniaxial crystal which initially has a specific multidomain structure, wherein light enters via predefined areas of the crystal, and wherein a magnetic field pulse having a magnetic intensity Hl is applied to the crystal (1), wherein the crystal (1) is transformed into a reversible monodomain state. In order to obtain an enlargement of the useful aperture, while at the same time keeping switching and response times to a minimum, a retention magnetic field of the same polarity and having a magnetic field intensity H2 is applied to the crystal (1) after transition of the crystal (1) into a reversible monodomain state, wherein the magnetic field intensity H2 is lower than the magnetic field intensity HI and the reversible monodomain state is maintained.
